The problem is that this patch implements only part of the suggestion, which isn't useful in itself. So the patch series should either drop this patch or consolidate the FDT allocation between the arches. I just tested on powernv and pseries platforms and powerpc can use vmalloc for the FDT buffer.Perhaps more sensible to use kvmalloc/kvfree.
That's true. Converting both arm64 to powerpc to kvmalloc/kvfree is a good option. I don't think it's that much better though, because kexec_file_load() is called infrequently and doesn't need to be fast so the vmalloc() overhead isn't important in practice. -- Thiago Jung Bauermann IBM Linux Technology Center _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
